Coherent Corp. (NYSE: COHR) recasts financials for new segment structure

Rhea-AI Filing Summary

Coherent Corp. is updating how it reports its business by moving to two operating segments, Datacenter & Communications and Industrial, effective with its 2026 fiscal year starting July 1, 2025. To align past disclosures with this new structure, the company is providing recast historical segment information for earlier periods and incorporating that information by reference into its other SEC filings, including registration statements.

The company has revised portions of its 2025 Form 10-K, including the Business, Management’s Discussion and Analysis, and Financial Statements sections, mainly to update segment and related note disclosures. Coherent states that these changes do not affect its previously reported consolidated financial position, results of operations, or cash flows and do not constitute a restatement of prior financial statements.

Item 8.01. Other Events.

As previously disclosed in a Current Report on Form 10-K dated August 15, 2025, effective with the beginning of its 2026 fiscal year on July 1, 2025, Coherent Corp. (the “Company”) began operating under two revised business segments: Datacenter & Communications; and Industrial. The Company’s businesses are organized and managed under two segments based on similarities in products and services.

The Company is filing information under Item 8.01 of this Current Report on Form 8-K (this “Form 8-K”) to (i) provide investors with recast historical financial information for periods prior to the segment change, and (ii) incorporate by reference that recast historical financial information into the Company’s filings with the Securities and Exchange Commission, including registration statements filed under the Securities Act of 1933, as amended.

The following items from the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025 (the “2025 Form 10-K”) are being revised and updated from their previous presentation solely to reflect the Company’s new segment structure, as reflected in Exhibit 99.1 to this Form 8-K:

•Part I, Item 1. Business;

•Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations; and

•Part II, Item 8. Financial Statements and Supplementary Data.

Except for minor, non-substantive revisions, only the following notes to the consolidated financial statements have been revised from their previous presentation:

•Note 1 - Nature of Business and Summary of Significant Accounting Policies;

•Note 3 - Revenue from Contracts with Customers;

•Note 6 - Goodwill and Other Intangible Assets;

•Note 14 - Segment and Geographic Reporting;

•Note 20 - Restructuring Plans; and

•Note 21 - Assets Held-for-Sale.

The changes referred to above had no impact on the Company’s historical consolidated financial position, results of operations or cash flows, and the recast financial information contained in Exhibit 99.1 to this Form 8-K does not represent a restatement of previously issued financial statements.

Also included in Exhibit 99.1 is the report of Ernst & Young LLP, our independent registered public accounting firm, on the consolidated financial statements, which is unchanged from the report included in the 2025 Form 10-K, other than the dual date to include the recast and reissuance of the consolidated financial statement footnote information.

This Form 8-K does not modify or update other 2025 Form 10-K information in any way, nor does it reflect any subsequent information or events, other than as required to reflect the change in segments as described above.

The information in this Form 8-K, including Exhibit 99.1, should be read in conjunction with the 2025 Form 10-K and any other documents filed by the Company pursuant to the Securities Exchange Act of 1934, as amended, subsequent to August 15, 2025, which are incorporated herein by reference.

FAQ
